Chalcone Derivatives As Corrosion Inhibitors for Mild Steel in Brine-Kerosene Solution

Abstract

The efficiency of (2E,4E)-1-(2-hydroxy-5-methylphenyl)-5-phenyl-2,4-pentadiene-1-one (1), (2E)-3-[2-(allyloxy)-5-bromophenyl]-1-(2-hydroxy-5-methylphenyl)-2-propen-1-one (2), (E)-4-methyl-2-(3-methyl-4-styryl-4.5-dihydrobenzoisoxazol-6-yl)phenol (3) and 2-{4-[2-(allyloxy)-5-bromophenyl]-3-methyl-4.5-dihydro-1.2-benzisoxazol-6-yl}-4-methylphenol (4) as corrosion inhibitors have been studied by weight loss measurements for St-3 mild steel specimen in brine-kerosene mixture. The corrosion rates of St‑3 steel decreased with increase in concentration of the studied compounds.
